[1] The SOLENE-microclimat model: Potentiality for comfort and energy studies, Marjorie Musy, Marie Helene Azam, Sihem Guernouti, Benjamin Morille, Auline Rodler, ISBN:[9783030654207, 9783030654214], Springer International Publishing (2021), doi:10.1007/978-3-030-65421-4_13

The SOLENE microclimat model has been developed to investigate the consequences of urban context on local microclimate and indoor thermal conditions. It is dedicated to modeling urban microclimate and building thermal behavior at the district scale. The modeling approach is based on the coupling of several modules: radiative, thermal, and CFD models. The model can simulate a large range of cases e...

[2] Urban microclimate and building energy simulation coupling techniques, Auline Rodler, Nicolas Lauzet, Marjorie Musy, Marie Helene Azam, Sihem Guernouti, Dasaraden Mauree, Thibaut Colinart, ISBN:[9783030654207, 9783030654214], Springer International Publishing (2021), doi:10.1007/978-3-030-65421-4_15

This chapter presents a review bringing a critical overview of the different ways in which the urban microclimate is currently considered in building design simulations. Therefore, different building energy models (BEMs) and urban climate models (UCMs) are presented. The ways these tools communicate are presented and the impact of UHI and the microclimate is assessed. For example, when conducting ...

[3] Macroelements for soil-structure interaction, Diana Salciarini, Stephane Grange, Claudio Tamagnini, Panagiotis Kotronis, ISBN:[9781786307989, 9781119887690], Wiley (2021), doi:10.1002/9781119887690.ch4

This chapter shows the potentiality offered by the macroelements for the quantitative evaluation of soil structure interaction (SSI) effects and compares the two alternative approaches in the formulation of macroelements (based on elastoplasticity and hypoplasticity). It presents the concept of generalized forces. The chapter provides the general formulation of the incremental constitutive equatio...

[4] Fundamentals of Bifurcation Theory and Stability Analysis, Ioannis Stefanou, Sotiris Alevizos, ISBN:[9781789450002, 9781119755203], Wiley (2021), doi:10.1002/9781119755203.ch2

Bifurcation theory and stability analysis are very useful tools for investigating qualitatively and quantitatively the behavior of complex systems without determining explicitly the solutions of its governing equations for various initial and boundary conditions. This chapter is an introduction to the corresponding mathematical theories. It provides the basic ideas of bifurcation theory and stabil...

[5] Numerical Modeling of Multiphysics Couplings and Strain Localization, Frederic Collin, Panagiotis Kotronis, Benoit Pardoen, ISBN:[9781789450002, 9781119755203], Wiley (2021), doi:10.1002/9781119755203.ch7

This chapter summarizes the main observations on localized phenomena and proposes numerical tools to characterize localization processes. To deal with interactions occurring between the different phases of porous media, a regularization technique based on the second gradient model has been extended to multiphysic couplings. The chapter describes the regularization methods used to properly model th...

[6] Instabilities Modeling in Geomechanics, Ioannis Stefanou, Jean Sulem, ISBN:[9781789450002, 9781119755203], Wiley (2021), doi:10.1002/9781119755203

Instabilities Modeling in Geomechanics describes complex mechanisms which are frequently met in earthquake nucleation, geothermal energy production, nuclear waste disposal and CO2 sequestration. These mechanisms involve systems of non linear differential equations that express the evolution of the geosystem (e.g. strain localization, temperature runaway, pore pressure build up, etc.) at different ...

[8] Multiphysics Couplings and Strain Localization in Geomaterials, Jean Sulem, Ioannis Stefanou, ISBN:[9781789450002, 9781119755203], Wiley (2021), doi:10.1002/9781119755203.ch8

This chapter reviews some multiphysics couplings which enhance strain localization in geomaterials. It focuses on shear banding, emphasizing thermal and chemical effects in relation with shear heating. A comparison between a rate dependent Cauchy continuum and a rate independent Cosserat continuum is shown for the scaling of the localized zone thickness. The comparison is made on the basis of a si...

[9] Mechanical states induced by Moisture Diffusion in Organic Matrix Composites: Coupled scale transition models, F. Jacquemin, S. Freour, ISBN:[9781617288579, 9781617611445] (2021)

Composite structures are often submitted to hygroscopic loads during their service life. Moisture uptake generates multi scale internal stresses, the knowledge of which, granted by dedicated scale transition approaches, is precious for sizing mechanical part or predicting their durability. Experiments report that the diffusion properties of penetrant organic matrix composite systems may continuous...

[10] Analysis of Instabilities in Faults, Hadrien Rattez, Ioannis Stefanou, Jean Sulem, Manolis Veveakis, Thomas Poulet, ISBN:[9781789450002, 9781119755203], Wiley (2021), doi:10.1002/9781119755203.ch10

In this chapter, the authors are interested in modeling the creation of shear bands within a fault zone by taking into account the influence of the characteristic size of the microstructure through Cosserat continuum theory together with thermo hydro mechanical (THM) couplings. Two approaches are considered to study the system of coupled nonlinear partial differential equations: linear stability a...
